- Understanding 2D Arrays
- 2D arrays are arrays of arrays that can grow both vertically and horizontally
- Elements are accessed using two indices: row and column
- 2D arrays are used in various applications like image processing and databases
- Methods to Create 2D Arrays
- Nested lists can be used to create empty 2D arrays without external libraries
- Dictionaries can be used as placeholders for array elements
- NumPy library provides convenient multidimensional array creation
- Creating Arrays with NumPy
- NumPy.zeros() method creates arrays loaded with zeros
- NumPy.array() creates ndarray objects
- NumPy.arrange() can convert lists to 2D arrays
- Important Notes
- Arrays can be reshaped into any shape as long as elements fit dimensions
- NumPy requires installation via pip
- Numpy.mat submodule specializes in matrix operations
